merge3(target, base, ours) applies only the base->ours delta; session reconcile is
(C0, B0, B1, lenient), in-place update is (realm now, synced snapshot, new canonical, strict).
Item/pet mappings gain presence (present/filtered/realm_local) so realm-filtered state is
told from player deletion. Updates are journaled like imports (marker + alloc row) and
recovered from the realm. Live tests cover filtered vs deleted items, checkpoints, pets,
conflicts, lost answers, atomic rollback and the A->B->A->B round trip without a server.

Reads one offline character out of a realm's characters database through the
existing Db abstraction: fixed SQL with the local guid as the only (numeric)
input, one consistent READ ONLY snapshot per character, hex-encoded text.
Maps the approved minimal v1 scope to the portable model; refuses online,
deleted, bot, active challenge/game mode/Manastorm and unknown-table cases.
Adds the 163-table registry, the settings policy, "Make Portable" in one store
transaction, and item mapping lifecycle with content identity (schema 2) so a
recycled local item guid never inherits an old portable item.
Recorded answers of a real MySQL drive the unit tests; live tests re-verify
them, read-only enforcement and snapshot consistency on a disposable server.
No realm database is written and nothing changes for existing installs.

- Server settings page gains 'CPU cores for the world' (MapUpdate.Threads), translated in all languages.
- On the first start of an installed server (not imports) the Manager sets it to half the logical processors (2..8) unless
the owner already raised it, and lowers Logger.network / Logger.entities.player from debug to info; once per server.
- tools/sample_stacks.py: sampling profiler for a running worldserver (dbghelp + PDB), used to find what the world thread spends time on.

Verified: 28 real config files round-trip byte-identical; native UI edit changes
exactly one line in template and generated conf; snapshot restore is byte-exact.

Verified on a disposable fixture: start reports world_db_incompatible for a
pristine DB with a newer binary; stop is graceful; live install untouched.
